I beleive I'm going to have to lap my PAL6035 because it has some scratches and dark spot on the contact surface. The temps are rather high after I got my replacement CPU since I crushed my first one. There's a strange spot on the surface where it made contact with the TBird die that almost looks like a scortch mark.
I've never lapped a copper based HS so I'm worried about it. How much will it wear it down? Should I do it or just buy a new one?
Also, I was considering using auto rubbing compound. Have a friend who used it on his and he said that it worked great on his HS. I have a kind that says it will remove 1500 grit scratches or finer. I'm mentioning this to try remove debris and any air pokets in between.
